Specification of Letters Patent.

Patented Feb. 25, 1913.

Application filed November 6, 1912. Serial No. 729,849.

To all 207mme't may concern Be it known that I, CHARLES L. Onsnn, acitizen of the United States, residing at Fitzgerald, in the county ofBen Hill and State of Georgia, have invented a new and useful Device forPreventing the Freezing of ater-Pipes, of which the following is aspecification.

The present invention relates to improvements in a device for preventingthe freezing of water under pressure in the main, the primary object ofthe present invention being the provision of a device adapted to beattached to a main or reservoir, in such a manner that the same will beplaced in the most exposed position to be affected by the loweringtemperature and contains a water container of less tensile strength thanthe usual conduit, so that the freezing of the water therein would burstthe same to relieve the water pressure and thus prevent freezing in themain or reservoir.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction. hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawingsFigure 1 is a side elevation of the complete device asconnected to a water pipe. Fig. 2 is a longitudinal sectional viewthrough the device at right angles to the position of the same as shownin Fig. 1.

Referring to the drawings, the numeral 1 designates a pipe or conduitwhich carries water under pressure and which it is desired to protectagainst freezing, the same having connected thereto by any suitablemeans, as shown, a nipple 2, the device 3 which will under freezingconditions release the water contained within itself to permit thedraining of the conduit 1 or the flowing therethrough of the water sothe same cannot be frozen while in mot-ion. This device is supportedfrom the end of the nipple 2 through the means of the bushing 4 whichhas connected thereto, a coupling member 5 interiorly screw threaded atboth ends and having connected in its lower end, the upper end 6 of thetubular frame 7 whose lower threaded end 8 is seated within and engagedby the plug or cap 9.

Mounted within the plug or cap 9 is a washer or gasket 10 which abutsthe lower end of the glass tube 11 whose upper end is seated upon theannular gasket or ring 12, which is disposed between the tube 11 and thelower end of the bushing 4c. The frame 7 is provided with cut awayportions which permit of the observation of the contents of the glasstube 11. As the glass tube 11 is purposely made of less tensile strengththan the conduit 1 and nipple 2, it is evident that when disposed in anexposed position that is in a. position where it will be affected moreby the rise and fall of the temperature than the conduit 1, that thefreezing of the water within the tube 11 will cause the bursting orbreaking of the tube and consequently the release of the Water pressurewithin the pipe 1 through the nipple 2.

It is apparent that this device may be attached to protect watercirculating systems of automobiles and also connections to steam boilersand the like.

It is evident from the foregoing that a very simple means is providedfor preventing the freezing of the water within the pipe 1 or any othermain or tank that may retain water under pressure, the tube 11. being sodisposed and constructed as to be readily. broken due to the freezing ofthe water therein and consequently before such water will freeze withinthe less exposed pipes 1 or 2.

What is claimed is:

1. A device of the character described, including a fragile tube of lesstensile strength than the water conducting pipe, a tubular supportsurrounding said fragile tube, a metal cap sealing the lower end of thefragile tube and carried by the tubular support, and means connected toth upperend of the tubular support for making a water tight joint at theupper end of the fragile tube and for connecting the device to a waterconduit.

2. The combination with a water conduit for containing water underpressure, of a device for preventing the freezing thereof, including ametal supporting member, a coupling member connected to the upper endthereof and for engagement with the water cDnduit, a fragile tube ofless tensile strength than the Water conducting pipe mountedconcentrically within the supporting member and having its upper enddisposed within the coupling of the supporting member, and a cap fittingupon the lower end of the supporting member and sealing the lower end ofthe tube.

3. The combination with a water conduit for containing water underpressure, of a device for preventing the freezing thereof, including ametal supporting member, a coupling member connected to the upper endthereof and for engagement with the water conduit, a fragile tube ofless tensile strength than the water conducting pipe mountedconcentrically within the supporting member and having its upper enddispose-d within the coupling of the supporting member, a cap fittingupon the lower end of the supporting member and sealing the lower end ofthe tube, and two gaskets, one fitted within the cap at the lower end ofthe fragile tube and the other within the bushing at the upper end ofthe fragile tube.

In testimony that I claim the foregoing as my own, I have hereto afiiXedmy signature in the presence of two witnesses.
